Question

Gabriela is sick with a bad cold. Her immune system is defending her body against the invading virus. The first line of defense is cells called macrophages, which attack viral particles. The cells eliminate viral particles in a process called endocytosis. Arrange the steps of endocytosis in order of what occurs.

1. Cell surface receptors bind to the viral particle.

2. Lysosome within the cell encloses the viral particle.

3. Viral particle is surrounded by the cell membrane.

4. Cell membrane curves around toward the cell's interior.

5. Lysosome's digestive enzymes destroy the viral particle.

6. Cell recognizes the viral particle as foreign material.

Please help, I am really stuck on this question.

Answer 1

Gabriela has coronavirus.
The first line of defense is basically based on the macrophages. macrophages or monocytes kills the virus by engulfing and digesting it in cell. The steps in endocytosis areas follows:
Cell surface receptors bind to the viral particle.
Cell recognizes the viral particle as foreign material.
Viral particle is surrounded by the cell membrane.
Cell membrane curves around toward the cell's interior.
Lysosomes within the cell encloses the viral particle.
Lysosomes's digestive enzymes destroy the viral particle.
